Description

Ironing plate in the form of a soleplate or ironing cup

The invention relates to an ironing board in the form of a Bügelei- sensohle or a heater plate with a plate body having a bracket side, wherein the plate body is made of an aluminum material, and wherein the plate body is made of a sheet metal and at least on the ironing side a mechanically resistant layer in the form of an electrochemical anodizing - having layer, which may be optionally coated with a layer Gleitmittel¬ and tenkörpers provides the ironing surface of the Plat¬.

Such ironing plates in the form of iron soles for ironing iron or in the form of bracket recesses for ironing machines, in which the material being ironed between a roller and a union in wesent¬ semi-cylindrical inner surface of the heater plate is smoothed, are diverse known. The strap plate each has a plurality of requirements are met, in particular with regard to the scratch resistance, corrosion resistance, particularly in applications in steam iron or Dampfbü¬ gelmaschinen, good sliding properties on the material being ironed, Abriebbe¬ resistance, temperature resistance and durability, even in terms of external appearance the ironing board. There have therefore hard coatings in the form of electrochemical anodic coatings see over ceramic coatings that are applied, for example by flame or plasma spraying, or other coverings enforced. Such anodic coatings in particular have a very good connection with the plate body to show high Abrieb¬ strength and do not tend to flake off.

Further ironing plates are known that are both made of Walzble¬ chen or the other as castings, after one injection-molded parts are manufactured. but have made of rolled sheets manufactured ironing boards a number of advantages, especially when combined with aufge¬ brought to the strap top anodic coatings.

Nevertheless, there is further sheet relative to improve electrochemical anodic coatings as a clip layer scratch resistance or at least the Lang¬ lebigkeit of the outer appearance with respect to scratches, as well as the corrosion resistance of the need of such ironing plates from Walz¬. To this end, the process parameters of the anodizing process, such as temperature,

Current density or pH of the anodizing bath to be changed, but this is always connected with compromises in terms of viel¬ fältigen mechanical requirements of the anodic ver¬. The same applies layer thickness for an increase in the anodizing as this are set for economic reasons boundaries and form a uner¬ wish thermal barrier to large layer thicknesses.

The invention is therefore based on the object, a Bügelplat- te to improve the ironing surface with electrochemical anodizing, in particular to the effect that this increased scratch resistance, or at least optically lower Wahrnehmbar¬ speed of scratches or other influences, and increased corrosion resistance and longer life has.

According to the invention the object is achieved by a strap plate, wherein in micropores of the electrochemical anodizing layer dyes, in particular color particles are incorporated to the externally perceptible coloration of the bracket side, and wherein the ironing surface has a macroscopic roughness in the form of irregular elevations and depressions, where the elevations are non-isometric and have an elongated shape. The surveys can be worked out of the sheet metal material here in particular already, taking into account be¬ that a subsequent anodizing to produce the hard material layer may also have an impact on the design of the surveys. The macroscopic roughness is preferably identifiable by visual inspection with the naked eye unbe¬. By providing a Bügel¬ plate with a macroscopic roughness, in which also dyes are incorporated into the micropores of the anodic coating, surprisingly, an ironing board with a deut¬ Lich increased service life and improved Korrosionsbeständig¬ can be provided ness. Moreover, scratches on the Bügel¬ are much more difficult to perceive plate, which is achieved by the combination of the inventive measures. Fer¬ ner, surprisingly, also a much improved corrosion behavior, by the above measures determined, which is attributed to the fact that on the one hand, the micropores are filled by the dyes in part, wherein the dyes accumulate in particular in each case at the bottom of the pores, so that a corrosive attack, for example by steam at steam iron to the base material of the plate body er¬ sword is. This effect is attributed to the fact that due to the surface structure of the strap plate Strömungskanä- Ie generated for air and / or water vapor and thus a er¬ facilitated shouldered removal of corrosive gases is made possible by the ironing surface, whereby the service life of the incorporated dyes is significantly increased. On the other hand, the formation of air cushions is tert between the elevations additionally by erleich¬ the macroscopic irregular roughness, which significantly improves the sliding properties. direct the WEI is by the incorporation of dyes in the micro pores in combination with the macroscopic roughness of the Bügel¬ side a surface structure created which beispielswei- se the visual perception of changes of the ironing surface due to local thermal overheating, corrosion or the like difficult. Further, an increased Chemikalienbe¬ is determined resistance, also just opposite Bügelhilfsmit¬ stuffs such as spray starches or lubricants are additionally applied to the material being ironed, to facilitate the ironing and / or to influence the properties of the material to be ironed after ironing the zu¬ during ironing, as the stiffness, the handle or the sensory properties of the material to be ironed during manual Ertas¬ th same. The life of the ironing plate is thereby increased overall significantly.

The coloring of the ironing plate is preferably such that can not be recognized by this, the original color of the anodic and / or of the plate body.

According to the invention embedded in the micropores dye may be present in particular in the form of colored particles or pigments. The dyes may be organic or inorganic dyes, in particular, organometallic pigments be, for example phthalocyanines, inorganic pigments such as Übergangsmetallcyanide or the like, that have sufficient thermal stability. In particular, the dyes transition metals such as nickel, copper, cobalt, iron, or the like can, although other suitable pigments can be used, for example, transition metal oxides or the like.

The respective dyes can cover at least partially or completely the wall of the micropore, preferably, the dyes are deposited on the base of the micro pores and fill the micropores of partially. Preferably, the micropores are not completely filled by the dyes. It has been found that the surface structure of the bügelgutseitigen surface in combination with the eingelager¬ th dyes surprisingly has a significant impact on the long-term stability and increased corrosion resistance of the ironing board and the optical perception of Bügeloberflä¬ che, eg in terms of perception of scratches or changes in Ironing surface due to thermal overheating of the ironing surface, tarnish, langzeitbeding- ter color changes or the like.

The macroscopic roughness is usually by visual inspection in the manner of a "orange peel" visually perceptible. The roughness is achieved by an irregular two-dimensional network of crossing grooves are formed by the gen inseiförmige Erhebun¬.

The non-isometric, elongated islands may extend along a preferential direction, which preferably corresponds to the longitudinal direction of the sole or the intended feed direction of the strap plate relative to the article being ironed. The preferred direction can also correspond to the rolling direction of the rolled sheet. The islands can also be oriented differently or randomly distributed. A part of the islands may also sentlichen essen- be isometric, preferably this fraction is small, for example <50% or <10 to 20% of the total area of ​​the ironing plate, or negligible. The ratio of length to width of the projections is preferably ≤ 10 or ≤ 20 or ≤ 50 and may or ≤ 5 ≤ 3 may be, preferably it is FER ner ≥ 2 ≥ 3 or ≥ 5 or ≥ 10 and may also be or twentieth The protrusions are preferably distributed irregularly over the entire ironing surface. The length of the projections is in each case many times smaller than the extension of the ironing plate in this direction, preferably ≤ 1/10 or 1/100 thereof.

The, the macroscopic roughness forming elevations can have an average height of> 5 μ from a base line, in particular ≥ about 10, or about 20 μ or more, preferably ≤ 25 or 50 μ or ≤ 100 μ have. It should be understood here is that the height and average height of the projections should be greater than the arithmetic means roughness value Ra. The protrusions may have an average longitudinal extent of ≥ 50 or ≥ 100 μ, in particular ≥ 250 or ≥ 300 or 400 μ comprise, for example, preferably ≤ 2000 or 3000 ≤ 1000 μ or μ, for example, about 500 μ. The Ab¬ stand of the projections in the longitudinal and / or transverse direction thereof can be approximately in the region of the expansion in each direction, or - in each case independently of one another - in the range of up to 25-50% thereof, or in the range up to 150- 200 % thereof, without being limited thereto.

The tips of the protrusions may suitable method such as grinding or polishing partially removed and thus be eingeeb¬ net. This processing can gel plate after inking of the Bü¬ or after fixation of the dyes or Aufbrin¬ supply carried an additional lubricant.

The macroscopic roughness is preferably partially or substantially completely layer by the support layer of the anodizing, in particular the plate body itself, provided, that is, base layer or plate body have corresponding Erhe- downs on. The bumps can be made of the roll sheet herausgear¬ be beitet and in particular by mechanical treatment such as brushing, sand blasting or grinding, or be produced immediately in the preparation of a roll sheet. Existing surveys of the roll sheet can also be a post-processing, in particular mechanically stronger herausgearbei¬ tet. The protuberances are also preferably in the form of elongated "humps" running or of irregular shape, and preferably have no angular boundary edges. Furthermore, the hump are substantially irregular or static distributed tistisch over the ironing surface. The projections correspond preferably with corresponding local modifiers - changes in the microstructure of the rolled sheet.

It will be appreciated that the macroscopic roughness or Uneben¬ standardize the ironing surface having a microscopic roughness Ra may be superimposed. The ironing side in this case has a preferred wise roughness Ra (arithmetic average roughness) of ≥ 0.75 or ≥ 1 μ, wherein the surface roughness Ra sierschicht to the anodization or may refer to the state ready for use of the Bügel¬ surface, wherein the may be anodic provided with a lubricant, but need not be.

It has been found that the surface roughness Ra (arithmeti¬ shear roughness), that is, the anodic oxide, optionally after applied lubricant coating, preferably ≥ 1.5 μ or μ ≥ 2, more preferably ≥ 3 μ. On the other hand too high surface roughness are not always an advantage so that the surface roughness is preferably ≤ 10 μ or ≤ 5 to 7.5 μ, wherein gegebe¬ may also be appropriate, higher surface roughness.

It has been found that the average roughness Rz and the maximum surface roughness Rmax is essential to be in order to completely ren definie¬ the surface structure that requires the advantages described above. Surprisingly, here is a "medium" roughness of the ironing plate opposite predominantly smooth, for example polished ironing plates beneficial. Thus, it has to be advantageous her¬ issued when the average surface roughness layer Rz of Anodisier¬ optionally tung according applied Gleitmittelbeschich-, ≥ 2 to 3 μ, preferably ≥ 5 to 1.5 μ, particularly preferably ≥ 10 μ weight. Too high average surface roughness Rz is not necessarily advantageous, so that the surface roughness Rz preferably ≤ 20 to 25 μ, is preferably in the range from 10 to 20 μ is.

Furthermore, it has proved advantageous if the maximum surface roughness Rmax of the anodised layer, optionally, is preferably applied by aufge¬ lubricant coating, ≥ 5 μ ≥ 7.5 to 10 μ, whereby, advantageously, the maximum height Rmax ≤ 25 to 30 μ, preferably ≤ -20 μ is, for example, is in the range 12 to 15

The ratio of average surface roughness Rz to the roughness Ra and the ratio of the maximum surface roughness Rmax to the Mit¬ tenrauwert Ra has also proven to be an important term might parameter for characterizing the ironing board of the invention. Here, have ratios of Rz Ra or Rmax Ra ≥ 3, in particular those found to be advantageous in the range of 3 to 8, or possibly even higher, more preferably 4 to 6 The ratio of Rz to Ra or Rmax to Ra is preferably in each case ≤ 10, preferably ≤ 8 be¬ Sonders, or more preferably ≤. 1

The value of maximum profile summit height Rp can be ≥ 2 μ, preferably from ≥ 3 to ≥ 4 ≥ 6 μ or μ, preferably Rp <10 to 15 μ. In particular, Rp can range from about 8 μ.

Furthermore, the supporting portion of the sole has been shown in each vorge given depths as may be, material parameters describing the strap plate according to the invention. The supporting parts are given hereinafter in each case as a percentage of total measurement range. The respective depths as the distance from the highest profile point into the material ben angege¬, wherein as a starting point 2% of the total roughness amplitude is set underneath the highest profile point (included in the other to define the contact ratio, the force on the filing DIN standards zoom pull). Preferably at a depth of 4 μ of the bearing portion 10 to 40%, preferably 15 to 30%, more particularly sondere about 20%. At a depth of 10 μ the part Tragan- is preferably about 50 to 90%, preferably about 60 to 80%, more preferably about 70%. At a depth of 2 μ of the support portion is preferably ≤ 30%, preferably ≤ 20 to 25%. On the other hand, the contact area ratio should be at a depth of 2 μ ≥ 5%, in particular about 10%. Preferably, the contact ratio is changed in the above-mentioned values ​​between a depth of 4 μ and a depth of 10 μ or, preferably, a depth of about 12 μ or beyond substantially linearly with depth. This results in a surface structure with a across the depth relatively uniformly changing Profi¬-regulation is provided, which Eigen¬ be stationary for the sliding and in connection with the incorporated dyes properties such as long-term stability, corrosion resistance, appearance, etc. It has proved advantageous. Further, it has proved advantageous if a deviation is determined the effect of a substantially linear relationship of the supporting portions to the depth at depths of less than 4 μ in that the support portions are higher than the part to the ratio Tragan¬ to depth for depths greater than 4 μ corresponds.

The roughness values ​​mentioned here are in each case determined in accordance with DIN EN ISO 4287, the tracing length used refers to DIN EN ISO 4288. All other information also refer to the valid date of filing DIN or ISO standards, unless otherwise indicated.

For the plate body are advantageously aluminum materials with a silicon content of ≤ 2 or ≤ 2.5 or ≤ 3 wt .-%, wherein the silicon content wt .-% is preferably ≥ 0.25 or ≥ 0.5 or 0.7, more preferably is in the range from 0.9 to 1.3 wt .-% or up to 1.5. It has been found that such alloys, materials for the storage of Farb¬ or of a fixing (see below) is particularly favorable pore structure and pore diameter in the anodization erge¬ ben, resulting layers so outstanding corrosion protection and long-term stable Deck¬. As alloys for panel material AlMgSiI for example, can be used. The total content of alloying elements other than aluminum is preferably ≤ 10 wt .-%, particularly preferably 5 wt% or ≤ ~ ≤ 2.5 -. 3 wt .-%.

Preferably, a fixing means is provided for fixing the dyes in the micropores, which is at least partially incorporated into the micropores. Preferably, the dye is completely abge¬ in the micropores covered by the fixing agent. Preferably, in this case fills the fixing agent the Mikropo¬ ren largely or completely. The dye can in this case be arranged substantially in the region of the bottom of the micropores, wherein the fixing agent in the micropores ein¬ stored the pore cross section fills at least a part of the pore depth or, preferably, the remainder of the Poren¬ volume of the micropores. Preferably, the financial covers xiermittel the dye to avoid cavities in the micropores from.

The fixing agent here is preferably a solid, but also gege¬ appropriate, a highly viscous oil with very low vapor pressure. Fixing agents are preferred on the basis of fluorescence ropolymeren, particularly Perfluoropolymeren as beispielswei¬ se polytetrafluoroethylene (PTFE), which have a high resistance and gives Temperaturbe¬ by good adhesion to the inner walls of the micropores a permanent enclosure of the dyes. The fixing agent may also be a gleitreibungsverminderndes agents, in particular, which makes this both the sliding properties of the ironing plate improves as well the dye is fixed in the micropores, whereby here fluoropolymers such as PTFE are also suitable.

the fixing agent is particularly preferably used polymer dispersion in the form of a solid, so that in each case a plurality of fixative can be stored in the micropores. To fix the dye, a dispersion is thus composed einge-, wherein a sufficiently high proportion of the means of Fixiermit¬ has a diameter which is smaller than the average pore diameter of the micropores. It is understood that after incorporation of the fixative ausge¬ the ironing plate a temperature and / or pressure treatment in the micropores sets may be to cause densification of the fixing agent in the micropores, so that the fixative as teil¬ or completely fused together can or are fused to the Poreninnenwandung.

The micropores of the electrochemical anodic oxide preferably have a mean diameter of ≤ 50 nm (500 angstroms) or ≤ ≤ 25-30 or 10-15 nm. Further, vor¬ are sufficient for a significant coloring of the ironing plate of the micropores with a diameter of ≤ 50 or ≤ 25-30 nm, wherein the proportion more than 10 or 20 vol .-% may be the total pore volume. By the incorporation of dyes and fixing means in such pores is clearly increased the Korro¬ sion resistance of the strap plate, as not penetration in her¬ kömmlicher way limited to the anodic oxide by sintering processes layers applied in such micropores. It is understood that the diameter of the micropores is influenced by the process parameters of the anodizing process as Tem¬ temperature, current density, pH value of the bath and by the gewähl¬ th base material of the ironing plate.

It is understood that the hard material layer with a cover layer zusätzli¬ chen a lubricant such. B. PTFE may be provided, wherein the lubricant layer covering the hard material layer completely or only substantially Vertie¬ the hard material layer can fill levies so that islands of the Hartstoff¬ layer remain between the lubricant-filled areas. Such lubricant topcoat may be gege¬ appropriate, provided in addition to the incorporated in the micropores fixative may be said lubricant topcoat sintered or also generated by application of a dispersion and a suitable post-treatment. By manufacturing the plate body made of a rolled sheet, it is preferably substantially free of pores, which can be produced particularly advantageous anodic coatings. It has further been found .that rolled sheets and in particular with respect to thermal and long-term stability of the dyes einge¬ superimposed in the micropores have significant advantages over gegen¬ castings. Particularly preferred, therefore, consists of the plate body made of a rolled plate whose surface is designed as unmit¬ telbar invention anodizing. Intermediate layers such as are produced for example by plasma or flame spraying, are preferably not present. Preferably the rolled sheet is attached directly without further arrangement of intermediate layers on the iron or with an iron block, for which purpose suitable fastening areas can be formed on a rolled sheet. However, it can also be provided without further intermediate layers, for example by a defined transition from the heated iron block to the ironing surface to generate out. It is understood that preferably the fabric roll structure of the sheet remains or in the production of the ironing plate of the rolled plate is at least partially or completely obtained in substantially optionally remains recognizable by transforming into another Gefügestruk¬ structure, for example by annealing.

The ironing plate may be on both sides and / or edges colored erfindungs¬ according to, in particular in each case by the Mi¬ kroporen embedded dyes, each in the Mikropo¬ ren at the same time fixing means for fixing the dyes are incorporated. Preferably the coloring and / or anodizing layer is on the supply side of the bracket side Befesti¬ facing away only partially applied, in particular Befes¬ actuating areas such as mounting locations for welding studs and / or heat transfer areas not for the thermal coupling of the ironing plate to a heater of the iron or the ironing machine, may be anodized and / or dye-free. Preferably, the anodic coating has a layer thickness of> 75 and ≤ 50 μ, preferably 10 to 40 μ, in particular about 20 to about 30 μ on. The anodic oxide forms this preference, directly a top layer on the plate body, without arrangement of intermediate layers.

Particularly preferably, the ironing plate of ironing or steam ironing machines can be used, for which purpose the strap plate breakthroughs in the form of vapor passage openings which can be brought into connection with a steam generating means of the iron or the ironing machine, or stand in Verbin¬ dung.

For the production of anodic coatings are known ren different Verfah, in particular anodising and hard anodising. Furthermore, other methods such as are. B. the Bengough method known which is capable of generating but erfindungsge¬ rectly ironing plates less suitable. For example, an anodising process can be used at a current density of 1.0 to 2.0 A / dm 2 and a temperature of about 2O 0 C of about 200 H 2 SO 4 g / l concentration using the sulfuric acid to form a anodizing to produce. It is understood that the process parameters mentioned can be suitably varied to renverteilung the optimum for the particular application polyvinyl / achieve pore diameter and roughness. The anodization is preferably performed under direct current, optionally with the AC. Preferably, the appropriate plate body blanks are anodized e- lektrochemisch without prior pickling or shine. The treatment bath may contain suitable dyes to be added in order to achieve an inking of the ironing plate, if appropriate, the plate body may be immersed in a dye bath after the preparation of the anodic oxide, whereby an electrochemical treatment of the plate-may be carried tenkörpers. After inking the plate body, a sealing of the anodic oxide can be carried out in a water bath having a bath temperature of 90 to 100 0 C for a suitable period, if appropriate, without this being necessary. Subsequently, by applying a dispersion of the fixing agent, z. B. an aqueous PTFE dispersion, the Fi¬ xiermittel be incorporated into the micropores. The Durchmes¬ ser of Fixiermittelteilchen may be chosen such that a sufficient proportion of fixative penetrating into the micropores, wherein the Fixiermittelteilchen otherwise deposited in recesses of the surface layer and completely fill the Vertiefun¬ gene more or less, or may form a durchge rising surface coating but what is not always necessary. The dyes and preferably also the penetrating into the micropores fixing means are therefore preferably over the entire surface of the bow-side Plat¬ tenkörpers or stored the total surface area of ​​the plate body insge¬ together with the same into the micropores. Subsequently hier¬ can be made to a heat treatment, optionally to evaporate the dispersant (eg water), and the fixing medium or lubricant particles by the heat treatment to each other and to be fixed to the plate body and the inner wall of the micropore.

In particular, the ironing plate of the invention has a favorable sliding behavior with saturated high wear and Chemikalienbestän¬ speed and meets high decorative requirements and is economical to manufacture. Furthermore, the ironing plate a very long life because the micro pores partially occluded dyes are permanently fixed in this and is also partially consumed by the fixing even at the onset of wear of the anodic oxide, wherein the Gleitmitteldeck¬ layer by the in-depth of the micropores embedded fixing agent / lubricant improved sliding action over long periods and at the same time corrosion is onsbeständigkeit achieved. The invention is described by way of example and illustrated by the figures.

Fig. 1 shows a schematic cross-sectional view of a detail of a bracket plate which can be formed as a soleplate for an iron, in particular a steam iron or a de Bügelmul¬ an ironing machine. The strap plate 1 comprises a plate body 2 from a AlMgSil alloy, which is in one piece and one layer made of a rolled plate, for example, by a stamping-embossing process. The Plattenkör¬ per coated directly with a hard material layer 3 (not shown to scale), which is produced by chemical anodization tion. The anodic coating is on both the bail side 4 and on the opposite, the overall housing of the iron / ironing machine facing Befestigungs¬ page 5 and the side peripheral edge of the plate body applied. Further Befesti¬ 5 are on the fastening side supply areas 6 sen or mounting the bracket plate to the Bügelei¬ of the ironing machine is provided, for example on the iron block of the same or to an intermediate member, which may also be coated. The attachment face 5 are in whole or at least the areas 6 preferably not anodized and / or not colored. The same applies to serving as a heat bridge 7 area for thermal Ankop- pelung to the heater of the iron to form a "nen Verbren¬" of the dye to be prevented. The areas 6 and 7 may also be arranged in the area of ​​the mounting side. The surface structure of mounting side has a much lower as opposed to the bail side or no macroscopic see roughness.

The anodised layer has a of the embodiment

Layer thickness of 25 μ, an arithmetic average roughness Ra of 4 μ, an average roughness Rz of 16 μ, a maximum surface roughness Rmax of 18 μ on. Further, the anodic oxide following structural units at the following depths (the supporting units are given in percent of the total measuring path, the zugehöri¬ gen depths specified in each case as the distance from the highest profile point into the material, wherein the starting point of 2% of the total rauheitsamplitude below the highest profile point angenom¬ is men): contact area ratio of 5%: 1 μ; 10%: 2,4μ; 15%: 3.1 μ / 20%: 3.8 μ; 30%: 5 μ; 40%: 6.3 μ; 50%: 7.6 μ; 60%: 8.9 μ; 70%: 9 μ; 80%:

11.0 μ; 90%: 12.3 μ; 95%: 13.3 μ; 100%: 15.6 μ. The roughness above as well as the support portions relate to the anodised layer with no arrangement of an additional cover layer, but may possibly also apply to a surface coated with lubricant anodizing. The incorporation of dyes and fixing agents in the micropores have no effect on the above information, practical. The average diameter of micropores of the anodic oxide is approximately 25 nm.

Figure 2 (not to scale) shows a detail of Anodi¬ sierschicht 3 having a micropore 10. The micropore is bounded at its base 11 to the plate body 2 out by a barrier layer 12th In the micropore 10, a dye is Gert eingela¬ 13, wherein the micropore and is gege¬ appropriate, also deposited on the pore wall 14 in the region of the base. 11 By a subsequent fixation step is on the dye of the bow-side surface facing a fixing separated off 16, which polymer (PTFE here) is formed in the form of dispersion of a fluoro. The fixing agent in this case includes the dye 13 in the micropore in wesentli surfaces without the formation of voids in the micro pores and fills the micropores 10 is substantially completely. It is understood that an adhesion of the fixing agent can be conveyed 16 on the pore wall 14 by a thermal aftertreatment.

Further, in the signals generated by the roughness of dimples 18 of the anodic oxide lubricant are also incorporated as for example PTFE, which are also applied in the form of a dispersion on the surface and permanently joined by means of removal of the Dispergiermit¬ and optionally subsequent thermal treatment with the surface. Lubricant 19 and fixing means 16 can hereby play represent the same substances as bei¬ PTFE, so that these rensschritt in the same Verfah applied to the surface, or can be incorporated into the micro-porous. Optionally, a the elevations of the ironing surface covering lubricant layer 15 may be provided, which can also handle finish completely bede¬ CKEN. Other surface areas 15 of Bügeloberflä¬ surface may be provided with lubricants such as PTFE.

Figures 3 and 4 show a schematic plan view of the ironing surface and a cross section IV-IV illustrating the macroporous roughness "genhaut Oran¬" by visual inspection as would be perceived. The superficial protuberances 21 can in the basic material 22 of the plate body by the may rolling process or subsequent processing such as grinding to be generated. The bumps are inseiförmig and form a network of grooves 23, and possibly also isolated Sen¬ ken, so that between the bracket plate upper side and ironed but a steam or hot air cushion created excess steam to escape. This is achieved a very good sliding properties, while also a very long life for the embedded dye. in addition, scratches are only difficult wahrgenom¬ men on this regularly irregular surface.

The elevations 21 may have an average height H of about 20 microns from the base line 24, and an average longitudinal extent of about 500 μ wherein they sensohle in the longitudinal direction of the Bügelei¬ or in swing direction (arrow) stretch er¬ as preferred direction. The extension of the protrusions in the transverse direction is significantly lower and approximately 1/10 of that in the longitudinal direction, so that the elevations are designed in the manner of "back". The lateral spacing of the projections from each other may be the lateral distance of the same sector.

By the incorporation of dyes in the significant roughness having anodic oxide is present in total an ironing plate which satisfies high decorative claims in which is makes the perception of scratches, which has a markedly improved corrosion resistance. In particular, by the incorporation of the dyes into the micropores at the same time be ensured by an optical quality control that surface throughout the ironing side Ober¬, which has a certain fracture due to the ridge-like elevations, the micropores are filled with dye, at least partially, and thus make an effective corrosion - is protected.
